Inspection and Maintenance Schedule

PRIOR TO EVERY USE
• Check that lanyard stop switch stops the engine.
• Check steering system for binding or loose components.
• Inspect the outboard for tightness to the boat transom. If any
looseness of the outboard or mounting fasteners exist,
retorque the outboard mounting fasteners to the specified
torque. When looking for signs of looseness, look for loss of
outboard transom bracket material or paint caused by
movement between the outboard mounting fasteners and
the outboard transom brackets. Also look for signs of
movement between the outboard transom brackets and the
boat transom (lift plate/setback bracket).
